chevy s10 xtreme std cab setup. my legs are killing me what to do?

okay here is my problem.i have a reg cab s10. it is a nice stereo setup, but i lost a little seat room/ to much. it is not from how the box is fitted, but when the sub hits and the thick surrounding im against it. i have 2 10s. one ten behind each seat and the amps in the middle on the amp rack. I tried to think of a bunch of crap to do to save my legs. my last idea! if i cut the back of the seat out, what does the inside look like? i was thinking of cutting a whole so the sub can actually be inside the middle somewhat of the seat! i know it might seem dumb or whatever, but help me out. just the face of the sub when it hits and all wouldnt be slammed against the back of the seat!
thanks
